For solving the problems of the technologies described above, the utility model adopts following technical scheme: equidistant Archimedes' helicoid wall thickness PCU, comprise base, and base is provided with substrate, and substrate is provided with and supports reference column and testing agency.
Described testing agency comprises locating device, faces nozzle body and cambered surface nozzle body directly, locating device comprises two guide rails that are set in parallel on the substrate, be provided with slide block between two guide rails, slide block and two guide rails are slidingly connected by the steel ball with retainer, slide block top is provided with locating piece, faces nozzle body directly and the cambered surface nozzle body is oppositely arranged on the locating piece both sides respectively.
Described guide rail two ends are respectively equipped with a baffle plate, are equipped with spring between two baffle plates and the slide block two ends.
The top, junction of described guide rail and slide block is provided with dustproof sheet.
The described puff prot that is equipped with two 0.3 * 3mm on nozzle body and the cambered surface nozzle body of facing directly.
Adopt said structure, the beneficial effect of generation is:
1. workpiece to be detected is placed on and supports on the reference column, utilize testing agency to measure fast between the two equidistant Archimedes' helicoids apart from (being wall thickness); Simple for structure, the automaticity height is increased work efficiency.
2. facing nozzle body and cambered surface nozzle body directly is arranged on the locating piece of locating device, can follow locating piece moves, but the wall thickness of measuring workpieces different parts is like this eliminated the influence that the profile errors because of Archimedes' helicoid causes wall thickness measuring, accurately wall-thickness measurement simultaneously.
3. baffle plate and spring play the effect of stable and support slipper.
4. dustproof sheet plays and prevents that dust from entering between slide block and the slide rail and have influence on being slidingly matched therebetween.
5. 0.3 * 3mm rectangular configuration of puff prot, the arcwall face of arcwall face nozzle body is parallel with Archimedes' helicoid, with the width of 0.3mm, eliminates face of cylinder simulation Ah basal plane moral helicoid and causes measuring error.
The utility model can be measured the wall thickness of the inner dynamic and static dish of scroll compressor fast, the measuring accuracy height, speed is fast, the efficient height, can realize the one-hundred-percent inspection of workpiece, the quality of the product of guaranteeing to dispatch from the factory experimental results show that, improve 10 times with this device than hand dipping speed, be worth applying in manufacturer.

Embodiment
Shown in Fig. 3～10, equidistant Archimedes' helicoid wall thickness PCU of the present utility model comprises base 1, and base 1 is provided with substrate 2, and substrate 2 is provided with and supports reference column 3 and testing agency.Testing agency comprises locating device, face nozzle body 4 and cambered surface nozzle body 5 directly, locating device comprises two guide rails 6 that are set in parallel on the substrate 2, be provided with slide block 7 between two guide rails 6, slide block 7 and two guide rails 6 are slidingly connected by the steel ball 9 with retainer 8, slide block 7 tops are provided with locating piece 10, face nozzle body 4 and cambered surface nozzle body 5 directly and be oppositely arranged on locating piece 10 both sides respectively, two guide rail 6 two ends are respectively equipped with a baffle plate 11, the top, junction that is equipped with 12, two guide rails of spring 6 and slide block 7 between two baffle plates 11 and slide block 7 two ends is respectively equipped with a dustproof sheet 13.Face puff prot 14 and the connecting hole 16 of fixedlying connected with locating piece 10 that nozzle body 4 is provided with two 0.3 * 3mm directly, cambered surface nozzle body 5 is provided with the puff prot 15 and the connecting hole 17 of fixedlying connected with locating piece 10 of two 0.3 * 3mm.
Thereby the utility model adopts the measuring principle that the gap S of nozzle-baffle mechanism is converted to the height H amplification demonstration of air-gauge buoy.When work is used, be placed on the support reference column 3 respectively two cover standard components and the location, wherein the standard ring wall of a cover is thick is the upper limit of measured workpiece (quiet dish) 25 wall thickness, another set of standard ring wall is thick to be that (standard ring radius nominal value is consistent with the radius-of-curvature of Archimedes' helicoid measured point for the lower limit of measured workpiece (quiet dish) 25 wall thickness, thereby eliminate the influence of error of curvature) to measuring, the supporting air-gauge that uses is QFB-A-2-2, can measure after utilizing two cover standard components calibration air-gauges.During measurement, use, the basic enlargement factor of lower limit calibration air-gauge, then measured workpiece (quiet dish) 25 is positioned over by the location and supports on the reference column 3, face two groups of puff prots 14 of nozzle body 4 and cambered surface nozzle body 5 and puff prot 15 (every group is the subtend puff prot) and measured workpiece (quiet dish) 25 wall thickness directly and constitute two nozzle-baffle mechanisms, because different measured workpiece (quiet dish) 25 wall thickness δ differences, when crossing puff prot 14 and puff prot 15 ejections, air communication cause the gap S of nozzle-baffle mechanism to change, be converted to the variation of buoy height H by air-gauge, thereby measure the wall thickness δ of quiet dish.Amount instrument reaction scheme is: Δ δ → Δ S → Δ H (annotate: the amount instrument is measured as comparative method for measuring, and Δ δ is the variable quantity of tested quiet dish wall thickness and standard component wall thickness in the formula).
